                                While mustard has a long history of use as a traditional cold remedy, particularly as a topical decongestant, there is very limited scientific evidence to support its effectiveness. The pungent compounds in mustard, such as allyl isothiocyanate, create a warming sensation that is believed to provide temporary relief from congestion.
